Stereo speakers for today's wireless sources

You don't have to choose between the convenience of Bluetooth and true high-performance sound. With the Nuforce S3-BT speaker system you can have both. It takes advantage of the latest advances in Bluetooth wireless technology to ensure that music sources like smartphones and tablets sound their best. Support for high-fidelity aptX® and AAC streaming technology means you can get near-CD sound quality from compatible devices. And these speakers sport a clean, modern design that'll look great whether you place them on your desktop or in an entertainment console.

A solid foundation

Of course, Nuforce knows that careful speaker design is essential, regardless of the source you're listening to. Each S3-BT speaker has a 1" silk dome tweeter for crystal-clear highs and a 3-1/2" woofer for clean, musical mids and bass. The system is driven by a built-in 18-watt x 2 Class D amplifier — plenty of power to get your tunes cranking.

Add a Nuforce Air DAC Wireless system (right), and you can stream music via Wi-Fi as well as Bluetooth.

Wired and Wi-Fi® options

A line-level RCA stereo input lets you connect another source, like a CD player or standalone DAC. (You could even connect your computer, using a stereo mini to RCA adapter.) The system also pairs up nicely with the Apple iOS® and USB versions of Nuforce's Air DAC system, which give you even higher-fidelity wireless 16-bit audio signal transfer. Just connect the Air DAC receiver to the speaker system via an RCA stereo cable.

Common BT problem

Check the reviews on other sites - common problem with these is with the bluetooth connection just dying. Mine worked for about 2 weeks, then the same thing; connect BT, start playing for about 2 seconds and then a loud buzzing sound comes from the speakers that doesn't go away unless you turn off/unplug the speakers. I'm 30-days in on my purchase today, I intend on returning

Solid Bluetooth speakers but not quite perfect

I'm using these in my bedroom with the Bluetooth feature and have not had any issues with the connection. These replaced a fairly high end iPod dock that had great sound but suffered form cabinet buzz/vibration on deep bass tracks. The bass on these is a little limited compared to the dock but the vibrations are gone making for a better listening experience. These have very clear highs and an overall warm and detailed sound. My one mark against these is that they are lacking somewhat in the midrange, which sound a little dull towards the upper end, though as I've used them more this seems to have improved somewhat.

Pros:Well built; Overall very good response for such small speakers; Bluetooth works well and setup is very easy.

Very good, not perfect.

Quick and easy setup. Bluetooth pairing is fast and stays from one session to next. Speakers sound with Bluetooth connection is very good, but there is a noticeable improvement with connected via included 3.5 mm jack (as expected). Sound is more warm than bright and quite balanced. Bass response is moderate, and can be improved with placement on a shelf or in corners. The speakers sound is far superior to portables units and they can play quite loudly without obvious distortion.

The only minor weak point is the Bluetooth connection. This is my second pair. The first sounded as described, but had frequent annoying dropouts (some prolonged). The new ones have this issue only occasionally and when it does occur, it is very brief and reconnects immediately. I notice no interference from other wireless devices nor any background hiss. Compared to my Jambox, the connection seems to be similar.

Nuforce S3-BT Bluetooth Speakers

I am using these on my desktop pc system which includes a mac pro tower, external DAC (Modi). sound is clear, powerful, and produces a reasonable low-end given a 3.5" woofer. I have not tried in bluetooth mode yet with IOS device. But will do so when I travel with them. good value for the money! Now my PC desktop reference system, plus mobile solution as well. I have them in white which looks nice.

Features

Overview: The NuForce S3-BT is an active loudspeaker featuring
Bluetooth wireless connectivity with aptX for high-fidelity sound reproduction. It
also includes stereo analog inputs for your non-Bluetooth devices and a USB charging
port for your smartphone or tablet. The S3-BT's compact bookshelf size fits almost
any room or decor. The speaker cabinet is wrapped in an elegant soft black or white
leatherette (with black cloth grilles).

Two-Way Speaker Design: Each NuForce S3-BT Bluetooth speaker
features a custom 1" soft-dome silk tweeter that offers a smooth and natural
response, and a 3.5" composite paper cone woofer with rubber surround which is
constructed using a proprietary "anti-resonance" cone technique and powerful
magnet assembly. The drivers are housed in a bass-reflex enclosure with a rear-firing
port.

Digital Amplifier: The NuForce S3-BT's right speaker employs
an efficient Class-D amplifier (18 watt x 2 channel) which powers all drivers in
the left & right speaker for clear, detailed sound and low power consumption.

Bluetooth aptX Codec: Bluetooth aptX, which is featured on a
growing number of Android mobile devices as well as MacBooks and Apple desktop
computers, allows audio to be broadcast wirelessly in significantly higher quality
than over standard Bluetooth. You'll instantly notice more extensive dynamic range,
deeper bass, and crystal-clear top end. Standard Bluetooth has an extremely variable
performance and its weaknesses are very apparent to music lovers. Common complaints
include a reduction in high-end clarity, muddiness or dullness in the midrange, and
its reduced signal-to-noise ratio can cause listener fatigue. Conversely, Bluetooth
aptX has a fixed performance standard to guarantee a consistently high-quality
wireless music transfer. With almost CD-quality reproduction to offer, you'll
instantly experience significantly greater dynamics and infinitely more detail
from your favorite music.

Compatible Music Sources: The range of music available from
today's iPods, smartphones, laptops, and computers is almost endless. In addition
to music stored on your iPod, smartphone, tablet or computer; online music services
likePandora,
iHeart Radio,
Spotify,
Rhapsody,
SiriusXM, and
of course other internet radio sources can be wirelessly transmitted to the
NuForce S3-BT.

SPP (Secure Simple Pairing): With Secure Simple Pairing (SSP),
you can easily pair a Bluetooth enabled device to the NuForce S3-BT without having
to enter pin codes or go through complicated settings. When a registered Bluetooth
device is in close proximity to the powered speaker, the auto connection function
automatically pairs the two units. Multiple Bluetooth-compatible devices can be
registered, but only one device can be used at a time. Due to the differences in
Bluetooth technology, some Bluetooth enabled devices may be incompatible, function
improperly, or may not support all features when used with the NuForce S3-BT.

Analog Inputs: The S3-BT's right speaker is fitted with stereo
RCA inputs for connecting an external audio device, which is not Bluetooth-enabled.
The stereo analog inputs can also be used for upgrading to the NuForce Air DAC
wireless system
(773AIRDAC,
sold separately) offering even more outstanding audiophile grade audio performance.

Binding Posts: The amplified right speaker is equipped with
binding-post speaker output terminals, while the passive left speaker is equipped
with binding-post speaker input terminals. A 10' length of speaker wire is included
to connect the two speakers.

Top-Panel Controls: The amplified right speaker features
top-panel controls. Control include - Source (Bluetooth/Line-in), Play/Pause,
Previous/Next Track, Volume Up/Down. The main power switch is located on the
rear-panel of the amplified right speaker.
